Lawyers who filed a lawsuit over the response to the Las Vegas massacre question why police and hotel and concert security officers didn't act more quickly to stop the gunman.

The lawyers held a news conference Wednesday alongside families of victims in the Oct. 1 shooting that killed 58 concert-goers and wounded hundreds more.

The attorneys want to know why six minutes passed without a police response from the time gunman Stephen Paddock strafed a hallway of the Mandalay Bay hotel with 200 rounds until he started killing people at the concert.

They also are perplexed about how Paddock was able to bring more than 20 rifles into his room without being detected.

Attorney Chad Pinkerton said authorities "should have done a better job and that's what this lawsuit is about."
